We work with TFS and Git. We modified the juicer code to preserve Visual Studio GUIDS and version control so it did not re-create it each time you save a project.
With the latest patch something in it broke. If we take the time to get it working again, is this something you would be interested in integrating, or would you prefer to do it yourself? (We don't know the JUCE / juicer system very well, so you might do a better job.)
basically, every time we use juicer to add files, when we save it, we use TFS command line to check out the .jucer file as well as the Builds/VisualStudioXXXX/ .vcxproj, .vcxproj.filters, files. We then preserve sections of those files when re-generating the files.
I am not sure which version we use, but we pulled it using Git on 10/8/2014.
If someone can tell me how to find the version I can reply.
